for my science fair project I did

what stain removal takes out stains the best!

not very scientific!!

but I actually won 3rd!!!

1. What condition is most favorable for decomposing an apple? Place three identical apples in zip lock bags. Add soil to one, water to another, and let the third simply be exposed to air. Watch the decomposition over three weeks. This project is an observation or demonstration, as the results cannot be measured. 2. What products in the home are made from recycled material? Gather items made from reclaimed materials and arrange them into an attractive display. This is a collection. 3. What kinds of birds live in Hawaii? Use books and the internet to research the answer to this question. Type up your findings and present them in a paper. This is a research project or a science report. 4. What temperature water is best for activating yeast? Fill three small bottles with water, one with hot, one warm and one cold. Add sugar and yeast to each bottle, and quickly place a balloon over the bottle mouth. Measure the tallest balloon to see which temperature activated the yeast. This is an experiment, or an investigative project. It follows the scientific method. 5. Make a model of DNA. Use craft beads and chenille wire to make a model of Deoxyribonucleic acid (DNA), the building block of life! This is a model.

I’m in 8th grade 2. A while ago we put alka seltzer (kinda like mentos) in a little film container and put water in it and shook it a few times then set it on the table. A few seconds later it shot off the table.

You could ask what would happen if I put alka seltzer/mentos in a container with water and shook it?

then what would happen if I used orange juice instead of the water?

If the project can be about anything, that would be kinda fun/intresting.

ITs fun and easy!

o that link is sweet. do this project:

“What will happen when you put milk in a dish, and drop 4 drops of food coloring in the North, South, East, and West sections of that same dish and when a toothpick is dipped in the middle with dish washing soap on the toothpick?”

do this expirement at you house and show it to your teacher. its the nicest project to ever doooooo.

How big will a gold fish grow?

I did this for mine in 8th grade. They grow bigger depending to the size of the tank they are in.

Good Luck

Hmmm, well you can show the effects of magma built up under the earths surface with diagrams and such, or something on the effects of pollution.
